Required Minimum Distributions (RMDs): Rules & Calculator

When you must start withdrawing and how to minimize the tax impact

Required Minimum Distributions force you to withdraw from your Traditional 401(k) starting at age 73 (or 75 if born 1960+). Roth 401(k) accounts are exempt from RMDs starting 2024 under SECURE 2.0.

RMD Start Ages (SECURE 2.0)

1960 or later75April 1 after turning 75

How to Calculate Your RMD

Divide your December 31 account balance by the IRS Uniform Lifetime Table factor for your age. For example, at age 73 the factor is 26.5, so a $500,000 balance requires an RMD of $18,868. Use our RMD calculator for your specific situation.

Missed RMD Penalty

SECURE 2.0 reduced the penalty for missed RMDs from 50% to 25% of the shortfall. If corrected within 2 years, the penalty drops to 10%. You can request a penalty waiver from the IRS by filing Form 5329 with a reasonable explanation.

Frequently Asked Questions

No. Starting in 2024, SECURE 2.0 eliminated RMDs for Roth 401(k) accounts. Previously, Roth 401(k) accounts required RMDs even though Roth IRAs did not. This change makes Roth 401(k) accounts more attractive for estate planning.

Yes, if you are still employed and do not own more than 5% of the company. The still-working exception lets you delay RMDs from your current employer 401(k) until you retire. It does not apply to IRAs or 401(k)s from former employers.

You can make Qualified Charitable Distributions (QCDs) of up to $105,000 per year from an IRA directly to charity, satisfying your RMD without increasing taxable income. QCDs are not available directly from 401(k) plans - you must roll to an IRA first.
